Behavior-based control of robot and trailer in hospitals

A behavior-based control system for mobile robot with trailer for navigating in constrained and dynamically changing environment in the presence of humans is presented. Constraints and features of such environment and critical situations in maneuvering are highlighted. An example scenario is discussed and shown. Two approaches of robot-trailer control, conventional controller and fuzzy logic based controller, are presented. A behavior-based control algorithm for safe and stable maneuvering in hospitals is proposed.
